Some of the agreements have environmental chapters or side agreements or annexes. The proof is in the pudding, so to speak, in terms of how well those are enforced and monitored and what kinds of rights they give for citizen engagement, for example, in all of the member countries. I agree that fundamentally we would like to see any trade agreements enhancing sustainability and not making it worse. In other words, the idea that we have a triple bottom line and not a single bottom line needs to be really internalized in a way that we haven't necessarily done in the past.
Specifically in the area of mining, Canada has learned a lot in terms of our past mining activities here in Canada in terms of legacy sites, and while more recent legislation is improving in some respects, we don't want to see that kind of activity repeated or those mistakes repeated elsewhere. We're well aware that tailings ponds, for example, can provide a significant risk, and we know all too well that when drinking water sources have sources of contamination that are not controlled, there can be real tragedy.
Those are the kinds of things that should be controlled.
